Abstract (en)
[origin: EP0374017A1] The present invention relates to novel silicates having an improved rate of dissolution, whose molar ratio SiO2/Na2O is greater than or equal to 1 and less than or equal to 4, and which have a density greater than 0.65 g/cm<3>. They consist of at least 90% of silicate and at least 1% of cellulosic derivatives.
